This study investigates the contamination of foods with Clostridium difficile in 3 hospitals of Central Italy. We used real-time PCR for tpi gene to analyse 350 food samples, including 296 cooked meals and 54 foods to be eaten raw. The molecular screening test was positive for 3 samples, but toxigenic C. difficile was isolated only in two of them. The prevalence in cooked food was 0,3% (1/296), while in uncooked processed foods was 1,9% (1/54). Data support the potential risk of food as a source of toxigenic C. difficile for hospitalized patients, but further investigations are needed.
本研究调查了意大利中部 3 家医院中食物中艰难梭菌的污染情况。我们使用 tpi 基因的实时 PCR 分析了 350 个食品样本，包括 296 份熟食和 54 份生食。分子筛选试验对 3 个样本呈阳性，但仅在其中 2 个样本中分离出了产毒艰难梭菌。熟食中的患病率为 0.3%（296 份中的 1 份），而未经烹饪的加工食品中的患病率为 1.9%（54 份中的 1 份）。数据支持食物作为产毒艰难梭菌感染住院患者的潜在传染源的风险，但还需要进一步研究。
